HYMENOPTERA small carpenter bees new species new synonymies taxonomy. Xylocopinae


The Neotropical species of the subgenus Ceratina (Zadontomerus) Ashmead are revised. We recognize seven new species, giving a total of 10 species for the region: Ceratina (Zadontomerus) capitosa Smith, C. (Z.) ignara Cresson, C. (Z.) nautlana Cockerell, C. (Z.) kopili new species, C. (Z.) basaltica new species, C. sapphira new species, C. (Z.) indigovirens new species, C. (Z.) rehanae new species, C. (Z.) raquelitae new species, and C. (Z.) tepetlana new species. We propose the following synonymies: C. abdominalis Smith, C. tehuacana Strand, and C. parignara Cockerell under C. (Z.) ignara; and C. bakeri Smith and C. nigriventris Friese under C. (Z.) nautlana. Also, we describe the previously unknown male of C. capitosa, and provide a key to the species, diagnoses, descriptions and illustrations of the new species.
